Purpose and Objectives Health care Professionals are at risk for exposure to bloodborne pathogens including hepatitis B (HBV), hepatitis C (HCV), and human immunodeficiency virus (HIV). You can be exposed through needle sticks or cuts from sharp instruments with infected blood, or through contact of the eye, nose, mouth or skin with a patient's blood. This course explains how you can protect yourself and reduce your risk of becoming infected from bloodborne pathogens in the workplace. After successful completion of this course, you will be able to: 1. Describe how blood exposures occur. 2. List ways to prevent exposure to bloodborne pathogens. 3. Name the types of isolation precautions used in the health care setting. 4. Describe the proper methods of hand hygiene and the use of gloves. 5. Name the three most common blood exposures and the accompanying risks. 6. Identify post exposure treatment options and follow up. How Blood Exposures Occur Bloodborne pathogens are infectious microorganisms, or germs in the blood that can cause disease in humans, such as hepatitis and HIV. Health care workers who are exposed to these germs risk serious illness or even death. Infection prevention measures are used in health care settings to decrease the risk of infections. In order for infection to occur, three things must exist: A source of infecting microorganisms A susceptible host A means of transmission for the microorganism to spread Source The source is where the infection starts. In health care settings, the source may be patients, employees or visitors who carry pathogenic microorganisms. Equipment can also provide a source of infection. Host The host is the person who is susceptible to, or who can catch the infection. A person s resistance to infection varies greatly. Factors that increase a person's risk for infections include age, other diseases and treatments. Transmission Infections are transmitted, or passed to another person in many ways. The same infection can be passed to another person in more than one way. To prevent transmission and risk of exposure to

3 infection, the CDC has developed precautions to protect patients and health care workers. Precautions include Standard, Contact, Droplet and Airborne Precautions. Health care professionals are at risk for bloodborne pathogens which include Hepatitis and HIV. A. True- Correct! Hepatitis B, Hepatitis C and HIV are infections which may be transmitted through blood. B. False Standard Precautions Standard precautions (also known as universal precautions) are practices designed to protect you and your patients from exposure to bloodborne pathogens (CDC, 2013a). These precautions should always be used when caring for ALL patients. Use Standard Precautions when you may come into contact with (CDC, 20130): Blood Semen Any body tissue Vaginal secretions Any fluid or tissue that comes from anywhere in the body Standard Precautions are used for all patients. A. True- Correct! Use Standard Precautions for all patients. B. False Types of Isolation Precautions There are several types of isolation precautions. These precautions will be a part of your daily work routine. Be familiar with your hospital's isolation practices. Although standard Precautions are routinely used for ALL patients, some patients with known or suspected infectious diseases may require additional precautions, which could be Contact, Droplet or Airborne Precautions. If a patient has a specific type of infection, other types of procedures are used. You may be asked to follow droplet precautions for flu patients. You will be asked to follow respiratory isolation for tuberculosis patients. You will use contact isolation for patients with certain resistant staph infections. Sometimes you may need other protective equipment to protect you during certain procedures. Personal Protective Equipment (PPE) may include goggles, masks, gowns and gloves to protect your mouth, nose, eyes, body and hands during certain procedures.

4 Always wear a gown if you think you might get splashed. Use the gloves, goggles, gowns and other protective equipment that are required for certain procedures or certain types of isolation. Please note! Use Standard Precautions for all patients. The following table summarizes the different types of isolation precautions. For a larger view of the chart, click here. How Can You Prevent Being Exposed to Blood? Each year more than 600,000 health care workers are injured with needles or sharps (other sharp objects) that have blood on them. Needle sticks and injuries with sharps put you at risk for becoming infected (RN.com, 2010). Use barrier equipment such as gloves, eye and face protection, or gowns when contact with blood is expected. This prevents exposure to the eyes, nose, mouth, or skin. Hand Hygiene Saves Lives Did you know that people typically carry between 10,000 and 10,000,000 germs on each hand? Proper hand hygiene is the most important action you can do to decrease the spread of infections. Wash Hands Before and after each patient contact After removing gloves After contact with any body fluid (blood, sputum, urine, etc.)

5 Alcohol-Based Hand Rub or Soap and Water? Alcohol-based hand rubs significantly reduce the number of germs on the skin. They act quickly, and cause less skin irritation than soap and water. Alcohol-based hand rubs take less time to use than traditional hand washing. If possible carry one with you for quick cleaning between patients. Use alcohol based hand rub only when hands are NOT visibly soiled. Click here to view Hand Hygiene Recommendations (CDC, 2013a) Please note! Proper hand hygiene is the number one way to prevent infection If you use an alcohol-based hand rub, you NEVER need to use soap and water. A. True B. False- Correct! Use alcohol based hand rubs only when hands are NOT visibly soiled. Alcohol based hand rubs do not kill spores. If a patient has C-diff or other infectious diarrhea like illness, use soap and water methods for hand hygiene. Hand Hygiene: Soap & Water versus Alcohol Based Hand Rub Soap and Water Method Wet hands with water, then add soap. Use friction to lather and wash hands for 15 seconds (try timing yourself by singing the Happy Birthday song). Rinse well under a stream of water. Dry hands thoroughly. Turn off the faucet with a paper towel. Extended wash times (greater than 15 seconds) are not required when patients are in isolation. Alcohol-Based Hand Rub Method Apply the product to palm of one hand. Rub your hands together (covering all surfaces of hands and fingers) until hands are dry. Note that the volume needed to reduce the number of bacteria on your hands varies by product. Do not touch equipment until hands are dry to prevent shock or burn. When washing with soap and water, scrub your hands for at least 15 seconds. A. True- Correct! Remember you can time yourself by singing the Happy Birthday song! B. False

6 Hand Hygiene and Gloves In health care settings, gloves are worn for three important reasons: To protect the health care worker from contamination from the patient. To protect the patient from contamination from the health care worker. To protect patients from contamination from the surrounding environment (other patients or objects). Gloves are the most important barrier to protect you from infection. It also prevents infections from being passed between patients. Wear gloves when caring for every patient. Change gloves between patients. Wash your hands immediately after taking the gloves off. Wearing gloves does not replace the need for hand washing. Gloves may have tiny microscopic openings or may be torn during use, resulting in contamination of the hands. Always use gloves as a barrier when working with patients to protect yourself. A. True- Correct! Gloves should be used when caring for every patient and change gloves between patients. B. False Sharps and Needles Special caution must be practiced to prevent injuries when using needles, scalpels, and other sharp instruments or devices. This includes handling sharp instruments during and after procedures, cleaning used instruments and using or disposing of used needles. Never: Recap used needles, or use any other technique that involves directing the point of a needle toward any part of the body. Remove used needles from disposable syringes by hand. Bend, break, or otherwise manipulate used needles by hand. Always: Place used disposable syringes and needles, scalpel blades, and other sharp items in appropriate puncture-resistant containers. Decrease or prevent splashing or spraying of blood or body substances when performing procedures. Never reach into a container with bare hands.

7 If you find a sharp container that is overly full, make sure that you put on gloves and carefully push down the needles on top so they are not exposed. A. True B. False- Correct! NEVER reach into a sharps container with your hands. Contact your supervisor immediately regarding this safety hazard. Sharps Disposal Disposable sharp items, such as hypodermic needles, require special handling because they are the items most likely to injure health care workers. If these items are disposed of in the municipal landfill, they are a danger to the community. The CDC (2013a) recommends the following practices when disposing of sharps containers safely: Wear heavy-duty gloves. When the sharps container is three-quarters full, completely seal the opening of the container using a cap, a plug, or tape. Be sure that no sharp items are sticking out of the container. Dispose of the sharps container by burning, encapsulating, or burying it. Remove the heavy-duty gloves. Wash your hands and dry them with a clean cloth or air dry. Work Practice Controls The workplace has many opportunities for exposure to blood or body fluids. Use PPE (personal protective equipment) such as gloves, masks, and face shields when: Disposing of waste and body fluids. Packaging lab specimens. Handling laundry. Cleaning contaminated equipment or material. Labels and signs are used on equipment to communicate hazards. They may be located on doors, refrigerators or other equipment. Facilities may use red bags or containers instead of signs or labels. Become familiar with the practices of the organization. What to do if you are Exposed to Blood or Body Fluids You have been exposed to blood or body fluids if you: Sustain a needle stick or sharps injury Receive a splash to your mucous membranes (eyes, mouth) Have broken skin (cuts, nicks) which has come into contact with blood or body fluids

8 WASH: Wash the exposed area immediately with soap and water. Rinse eyes or mucous membrane with normal saline if available, or with water. REPORT: Report the incident to your immediate supervisor and organization per P&P. GO: Go to Employee Health or Emergency Department as soon as possible, and follow the organization s policy and procedures. You are changing the bed linen of your patient when you feel a small prick and then notice a small needle lying on the linen. The next best action for you is to WASH-REPORT and GO! A. True- Correct! You have a suspected blood exposure and should follow your organization s procedure. B. False Post-Exposure Evaluation and Follow-Up Follow-up care should include: A confidential medical evaluation documenting the circumstances of exposure. Identifying and testing the source individual if appropriate. Post-exposure treatment / prophylaxi (PEP). Treatment should begin as soon as possible, ideally within one to two hours and no more than 72 hours after exposure. Counseling and evaluation of reported illness. Calling the Workers Compensation office to submit a claim. Immunizations to Prevent Infection The CDC recommends that health care professionals receive a number of standard immunizations. Since health care professionals are at risk for exposure to and possible transmission of vaccine-preventable diseases, maintaining immunity is an essential part of prevention and infection control (CDC, 2013a). Recommended vaccinations and testing include: Hepatitis B Influenza Tetanus Measles Mumps Rubella (MMR) Meningococcal varicella Tuberculosis

9 Hepatitis B The word hepatitis means inflammation of the liver and also refers to a group of viral infections that affect the liver. HBV is spread in health care settings when blood or other body fluid from an infected person enters the body of a person who is not infected, usually through contaminated needles, syringes, or other sharp instruments. The virus, which is called hepatitis B virus (HBV), can cause lifelong infection, cirrhosis (scarring) of the liver, liver cancer, liver failure, and death. Hepatitis B Facts In 2009, an estimated 38,000 persons in the United States were newly infected with HBV. Rates are highest among adults, particularly males aged years. HBV is spread when blood from an infected person enters the body of a person who is not infected. Health care personnel who have received hepatitis B vaccine and developed immunity to the virus are at virtually no risk for infection. OSHA requires health care professionals to participate in the vaccination program unless they sign a declination, have been previously vaccinated, have documented immunity, or have documentation of medical reasons why the vaccine is contraindicated. Some individuals who contract hepatitis can become carriers, passing the disease along to others. Carriers also face a significant risk for other liver diseases, including cirrhosis and liver cancer. Hepatitis C Hepatitis C is a liver disease caused by the hepatitis C virus (HCV), which is found in the blood of persons who have this disease. HCV is spread by contact with the blood of an infected person. The spread of HCV from one person to another in health care settings is rare, but can occur. Persons who can be exposed to HCV in health care settings include patients and health care personnel. Hepatitis C Facts The average risks for infection after a needle stick or cut exposure to HCV infected blood is approximately 1.8%. There are no exact estimates on the number of health care personnel occupationally infected with HCV. However, studies have shown that 1% of hospital health care personnel have evidence of HCV infection. There is no vaccine against hepatitis C and no treatment after an exposure that will prevent infection. For these reasons, following recommended infection control practices to prevent injuries are imperative. HIV Health care personnel are at risk for contracting Human immunodeficiency Virus (HIV). Exposures occur through needle sticks or cuts from other sharp instruments contaminated with an infected patient's blood. Exposure also occurs through contact of the eye, nose, mouth, or skin with an infected patient's blood.

10 HIV Facts Most exposures do not result in infection. Important factors that influence the overall risk for occupational exposures to bloodborne pathogens include the number of infected individuals in the patient population and the type and number of blood contacts. Transmission of HIV to patients or employees while in health care settings is rare, however proper sterilization and disinfection procedures are required. There is no vaccine against HIV. However, studies suggest that the use of antiretroviral drugs after certain exposures may reduce the chance of HIV transmission. Post exposure prophylaxis (PEP) is recommended for certain occupational exposures that pose a risk of transmission. Conclusion Hepatitis B virus is largely preventable through vaccinations. Recommended vaccinations and disease testing should be followed to best minimize the risk for acquiring a bloodborne pathogen infection. For Hepatitis C and HIV however, preventing exposures to blood can help to prevent infections. For the Certified Nursing Assistant, it is imperative that appropriate barriers are used when caring for patients such as the use of gloves, gowns and eye equipment. Always use any or all of your personal protective equipment. Assure that you follow controls set up in the work place such as proper waste disposal and handling and packaging of specimens. Always use safe handling techniques when working with sharps and needles and use all safety devices provided on equipment.
